Knee bends painful how is standing not painful to return a responsibility

Knee pain may be caused by meniscus injury, or other causes, such as patellar softening, synovitis, ligament injury, knee infection, osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, etc. It is recommended to seek medical attention promptly, conduct detailed examination and diagnosis, and take appropriate treatment measures after clarifying the cause. According to the information you provide, it may be caused by meniscus injury. Meniscus is a fibrocartilage structure located inside the knee joint, and its main function is to increase joint stability and buffer pressure. After meniscus injury, knee pain, swelling, limited movement and other symptoms can occur. When meniscus injury occurs, during knee flexion and extension, the damaged meniscus will rub against other structures of the knee joint, causing pain.

In addition, meniscus injury may also be accompanied by knee interlocking, ringing and other symptoms. It should be noted that there may be many causes of knee pain, such as patellar softening, synovitis, ligament damage, knee infection and so on. Therefore, if knee pain occurs, especially if it is accompanied by symptoms such as limited mobility, you should seek medical attention promptly, undergo detailed examination and diagnosis, identify the cause, and take corresponding treatment measures. For the elderly, especially postmenopausal women, the possibility of knee osteoarthritis also needs to be ruled out. Osteoarthritis is a degenerative disease, mainly related to age, obesity, strain, trauma and other factors. The main pathological changes are the wear and destruction of articular cartilage, which leads to knee pain, swelling, deformity and other symptoms. If osteoarthritis is suspected, X-rays, CT, magnetic resonance imaging (MRI) and other examinations may be needed to confirm the diagnosis. For young people, knee pain also needs to rule out the possibility of some special diseases, such as rheumatoid arthritis, ankylosing spondylitis, etc. These diseases can cause knee pain in addition to other symptoms, such as joint swelling, deformity, fever, fatigue, etc. If these diseases are suspected, blood tests, autoantibody tests, etc. may be needed to confirm the diagnosis. In short, knee pain is a common symptom, but its causes may be varied. If knee pain occurs, especially with symptoms such as limited mobility, seek medical attention in time for detailed examination and diagnosis to clarify the cause and take appropriate treatment measures.
